Singidunum

Singidunum, formerly known as Singidun, was an ancient city located on the site of present-day Belgrade, Serbia. It was settled by the Scordisci following the Gallic invasion of the Balkans in the 3rd century BC, and the area was conquered by the Roman Republic in 75 BC, being added to their province of Moesia. It was an important fort of Legio IV Flavia Felix after 86 AD, and the Roman emperor Jovian was born there. Singidunum was conquered by the Huns in 441 AD and by the Avars and Slavs in 584 AD, and, at the beginning of the 7th century, the Singidunum fort was destroyed. Singidunum eventually evolved into the Slavic city of Belgrade, now the capital of Serbia.
